Economic impacts from invasive species, conveyed as expected damages to assets from invasion and expected costs of successful prevention and/or removal, may vary significantly across spatially differentiated landscapes. We develop a spatial-dynamic model for optimal early detection and rapid...

Biocontrol, the introduction of organisms to control an unwanted species, has been cited as a powerful method to manage the invasive species Miconia calvescens in Hawaii. In addition to ecological advantages, biocontrol is often regarded as less costly than traditional methods despite the large...

We optimize groundwater management in the presence of marine consequences of submarine groundwater discharge (SGD). Concern for marine biota increases the optimal steady-state head level of the aquifer. The model is discussed in general terms for any coastal groundwater resource where SGD has a...

We provide a synthesis of the economics of groundwater with a focus on optimal management and the Pearce equation for renewable resources. General management principles developed through the solution of a single aquifer optimization problem are extended to the management of multiple resources...

This essay examines the current dispute between state and local governments in the U.S. and online travel companies (OTCs) over the appropriate hotel occupancy tax base for online hotel bookings. It addresses the question of what should be the appropriate tax base in designing hotel occupancy...

Tourism demand elasticities are central to marketing, forecasting and policy work, but the wide array of occasionally counterintuitive estimates produced by existing empirical studies implies that some of those results may be inaccurate. To improve the precision of estimates, it is natural to...

ChinaÕs ÒApproved Destination Status (ADS) policy allows citizens of mainland China to take pleasure trips abroad on group package tours to countries that have negotiated and implemented agreements with China. In this paper, we examine the reasons for this unique preferential and incremental...
